Selena Gomez has become the target of death threats after she was pictured frolicking with boyfriend Justin Bieber in Hawaii. The 18-year-old Disney actress has been singled out online by jealous fans of the teen pop idol — with some vowing to kill her. One Bieber fan wrote on Twitter: "I'll kill you I swear on GOD!!!!" Another promised: "If you are the Girlfriend of Justin I will Kill you I HATE YOU :@ !!!" Yet another fan of Bieber, 17, wrote on the site: "Stay away from Justin paedophile." Other comments included: "Selena Gomez is dangerously close to a long, slow painful death" and "I'm gonna kill ya in the night underneath your smell bed." The so-called Beliebers  hardcore fans of the 'Baby' singer  became enraged after the couple made their relationship public.
